yeah you have to show your insurance certificate when buying tax. or a cover not will also do. They arent supposed to accept faxed ones so I'm told but I have got tax in the past with a faxed cover note.
I think they are getting a bit strict about it latley. Most insurance companies can get you out a certificate of insurance or cover note within 48hrs. Edit - ha ha. you beat me too it!! Edited by: GajMk1
i think i may have had either photocopied or faxed covernotes accepted in the past... can't remember, but you do need insurance to get tax
